Abstract
Motion pictures or other digital media content can be encoded with visible, yet obscured, digital codes that can be optically detected by a camera or other automated image processing device. If a code is recognized in captured media content, further capture, playback and/or distribution can be halted, as desired. Because the code is visible (albeit hidden) in the digital imagery itself, capture by another camera or other optical device will not typically negate the usefulness of the code. That is, the code is visibly present within the imagery itself, so subsequent capture of the video imagery will also capture the code, thereby allowing for detection and/or prevention.
